Shell oblong-ovate, umbilicate, thin, shining, straw-colored, 

 subtranslucent ; with 5y 2 rather ventrieose whorls, impressed 

 at the sutures, ornamented with close, clear, fine, arched, 

 transverse striae; aperture oval; peristome thin, simple, tri- 

 angularly reflexed over the narrow umbilicus ; columella and 

 callus white, the former being slightly curved inwards at the 

 base. Length 6.5, width 2.75 mm. (Burnup).

This pretty little species is more elongate and slender than

1 i This delicate little shell, though much resembling in gen-

 smoother surface, less ventricose whorls, and shallower
